Each team member must collaborate and contribute to the project. Only one submission of the completed project (per team) is required.

CASESCENARIO(REFERTOPAGE291OFYOURTEXTBOOK)

Large Company database stores data for a company that sells paints. The company tracks the sale of products to customers. The database keeps data on customers [LGCUSTOMER], sales [LGINVOICE], products [LGPRODUCT), which products are on which invoices [LGLINE], employees [LGEMPLOYEE], the salary history of each employee [LGSALARY_HISTORY],

Page2of21

departments [LGDEPARTMENT], product brands [LGBRAND], vendors [LGVENDOR], and which vendors supply each product [LGSUPPLIES] as shown in the ER diagram below.

Historical data for this company in stored in a Microsoft Access database. Some of the tables contain only a few rows of data, while other tables are quite large; e.g. there are only eight departments, but more than 3,300 invoices containing over 11,000 invoice lines.
